24 Check headlight alignment
The alignment of headlights should be checked in a Volvo workshop after every
6,000 miles (10,000 km). Remember that the section of the road lit up by the
headlights can vary depending on the loading of the car.
Replacement of bulbs
The replacement of bulbs in the various lighting units is shown on the following
pages. Some of the bulbs have two functions, for example the headlight bulbs which
have filaments for both full and dimmed lights. The guide pins on the sockets of these
bulbs are either of different thickness or they are staggered so that the bulbs can only
be fitted in one determined position. Certain makes of bulbs have a “Top” mark which
should be turned upwards.
When fitting bulbs, you should never touch the glass with your fingers. The reason for
this is that grease, oil etc. can be carbonised by the heat from the bulb and this
cause damage to the reflector.
REPLACING THE HEADLIGHT BULBS
1. Loosen the screw on the underside of
the rim with a screw driver
2. Pull out the bottom part of the rim
slightly and lift upwards so that the
retainer catch releases it’s grip.
3. Loosen the three screws retaining the
inner ring (upper picture). These
screws do not need to be completely
removed. The inner ring can nthen be
removed by turning it in an
anticlockwise direction. Then lift out
the insert.
4. The insert is more convenient to deal
with if the cable plug is removed
(centre picture)
5. Loosen the spring which retains the
bulb holder.
6. Take out the bulb holder and loosen
the bulb by pushing it inwards and
then turning it in a clock-wise
direction. When fitting the new bulb,
remember that the pins on the socket
have different widths.
7. When the bulb holder is being re-
fitted in the insert, make sure that the
little catch engages in it’s notch.
